CHARLES C. HAYES, OF PENN YAN, NEV YORK.

TWO-WHEELED VEHICLE.

SPECIFICATION forming part -of Letters Patent No. 462,254, dated November 3, 1891.

Application filed September l5, 1890. Serial No. 365,072. (No model.)

To' @ZZ 'whom t may concern:

Be it known that I, CHARLES C. HAYES, a citizen of the United States, residing at Penn Yan, in the countyof Yates and State of New York, have invented certain new and useful Improvements in Two \Vheeled Vehicles; and I do hereby declare that the followingis a full, clear, and exact description of the saine, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

Figure 1 of the drawings represents a side elevation of the body of a road-cart with my improved spring attachment applied thereto; Fig. 2, a top plan view showing the body in dotted lines and one of the shafts connected to the axle; Fig. 3, a detail View showing the manner of attaching the shaft to the axle, and Fig. -i a detail view in perspective of the plates for attaching the shaft to the axle; Fig. 5, a perspective view of a modification thereof.

The present invention has relation to roadcarts or other two-wheeled vehicles, and is designed more particularly 'as an improvement on my former patent granted March 25, 1890, No. 424,297; and the object of the invention is to improve the mannerof supporting the body of the vehicle, also in the attachment of the shaft to the axle, whereby a more perfect running' vehicle is provided, which has superior advantages both in ease and comfort as well as increased durability, which objects are attainedy by the construction substantially as shown in the drawings and hereinafter described and claimed.

In the accompanying drawings, A represents the body of a road-cart of the usual oonstruction, upon the under side of which is connected in any suitable and Well-known inannera transverseshaft or spring B. I have shown a spring in the present instance as being more preferable; but a rocking shaft or rod may be substituted without departing from the principle of my invention. The

spring or rod, as above described, is of sufcient length that its ends will extend out beyond the sides of the body A, to which are attached in any suitable manner the ends of scrollsprings C. The opposite ends of the seroll springs are connected to the ends of semi-elliptic Vsprings D, and the latter-mentioned springs are secured to the body A directly under the' seat, as shown in Fig. 1.

The axle represented at E is connected to the scroll-springs .C by means of suitable clips a, and to this axle are connected the shafts F by means of the plates G l-I and the clip h.

The plates G II are bolted or otherwise attached to the shafts F,and are of suchleugth as to extend somedistance beyond the rear ends of the shafts, as shown in Fig. The upper one of these plates is connected to the axle by means of clip b, or any other desirable and well-known means may be employed for attachment of the plate to the axle. The plates G II are curved at their inner extremities, as shown at e, and have holes o, through which passes a headed bolt I, which has` screwthreads to .receive a nut (Z.

With the above-described means of attaching the shafts to the axle the body can be raised or lowered by tightening up the bolt or loosening it, as the case may be, thereby causing the body to ride level with a large or small horse and give play between the plates, also doing away with the so-called horse motion by the employment of the scrollsprings and connecting them to the semi-elliptic springs, thus providing a long and easyriding spring, which does away with the attachment to the cross-bar in road-carts of ordinary construction. As the vehicle-body is supported by the springs C and said springs in turn connected to the axle and the axle to the plates G, it will be seen that any change of position of the axle will likewise change the position of the vehicle -body. Now by screwing up or loosening the nuts on the bolts I the plates I-I will be lowered or raised to a slight degree from a horizontal posit-ion, and consequently the axle will be inclined correspondingly. This inclination of the axle, although but a slight degree, will materially change the position of the vehicle-body by inelining it at an angle either forward or backward, as the case may be, and to insure the adjustment of the plate II said plate has sufficient spring or elasticity for the purpose, while the plate G remains stationary or is rigid and is not affected by the adjustment of the lower plate. It will be seen that the plates G Il extend back of the axle E and the IOO adjustment is made at the rear thereof, thereby materially facilitating the operation.

In Fig. 5 I have shown a modification ofthe lower one of plates, which in the present instance extends upward and terminates in a screw bolt or shank, as shown, which is considered an equivalent to the construction shown in Fig. 3. Itis deemedimportant that the free ends of the plates G and H be curved, as seen in Figs. 3 and 4, to form depressions for the reception of the head of the bolt and the nut, or nut alone, in the form shown 1n Fig. 5, whereby the nut is less liable to become loose, the curve of the metal forminga sortof spring-retainer, against which the edges of the nut impinge, and, besides, the nuit is less liable to be turned or Worked loose by contact with anything. I deem itimportant that A the plates G and H be each independent of the other and each of a single piece, whereby greater elasticity is provided.

Having now fully described Iny invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with the shafts, of the plate G in a single piece secu red at one end to the rear end of the shaft and having its free end formed with a curve and depression, the axle secured to the plate to the rear of the shaft, the spring-plate H, secured to the under side of the shaft at one end independent of the plate G, curved under the axle, and its rear end extended upward and threaded and passed through a hole in the depression of the plate G, and a nut on the threaded end of said plateI-I and seated inthe depression of the plate G, Which forms a retainer for said nut to preventits Workingloose, substantially as shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the-presence of tWo Witnesses.

CHARLES C. IIAYS.
